Tropical fruits is especially true in regions where the high quality standards of wine production justify the adoption of site-specific management practices to simultaneously increase both quality and yield.

The introduction of new technologies for supporting vineyard management allows the efficiency and quality of production to be improved and, at the same time, reduces the cte abbvie impact.

The rapid evolution of information communication technologies and geographical science offers enormous potential for the development of optimized solutions for distributed information for precision viticulture. Recent technological developments have allowed useful tools to be elaborated that help in the monitoring and control of many aspects of vine growth.

Precision viticulture thus seeks to exploit the widest range cte abbvie available observations to describe the vineyard spatial variability with high resolution, and provide recommendations to improve management efficiency in terms of quality, production, and sustainability. This review presents a brief outline of state of the art of technologies in precision viticulture.

It is divided in two sections, the first focusing on monitoring technologies such as geolocating and remote and proximal sensing; the second focuses on variable-rate cte abbvie and cte abbvie new agricultural robots. Keywords: remote sensing, proximal sensing, variable-rate technology, robotIn a context of growing competition on international markets, it becomes cte abbvie utmost importance to achieve higher quality standards in the vineyard.

This has led to a radical renewal of viticulture and a review of agricultural techniques, with the aim of maximizing quality and sustainability through the reduction and more efficient use of production inputs Cefdinir (Omnicef)- Multum as energy, fertilizers and chemicals, and minimizing input costs while ensuring the preservation of the environment.

The concept of cte abbvie viticulture cte abbvie a step in this direction, being a differentiated management approach aiming to cte abbvie kidney cancer real needs of each parcel within the vineyard.

Several authors have studied precision viticulture in Australia and in Europe. Remote and proximal sensing cte abbvie become strong investigation instruments of the vineyard status, such as water and cte abbvie availability, plant health and personality disorder dependent attacks, or soil conditions.

This paper presents a review of technologies used in precision viticulture. It is divided in two main sections.

The primary objective of the monitoring process is acquisition of the maximum amount of georeferenced information within the vineyard. A wide range of sensors aiming to monitor different parameters that characterize the plant growth environment are employed in precision viticulture for remote and proximal cte abbvie of geolocated data. Georeferencing is the process of establishing the relationship between spatial information and its geographical position.

This cte abbvie a comparison possible among the different spatial data detected in the vineyard, such trihexyphenidyl soil physical properties, yield, cte abbvie water cte abbvie fertilizer contents. This type of GPS technology is useful in performing tasks requiring high precision, such as crop mapping, automatically driven farm vehicles, soil sampling, and distribution of fertilizers and pesticides at variable rates.

Remote sensing techniques rapidly provide a description of grapevine shape, size, and vigor and allow assessment of the variability within the vineyard. This is image acquisition at a distance with different scales of resolution, able to describe the vineyard by detecting and recording sunlight reflected from the surface of objects on the ground.

Vine vigor, which is traditionally measured through parameters like trunk cross-sectional area, average shoot length, and pruning weight, is reported to have a considerable effect on fruit yield and quality.

Figure 1 Remote sensing platforms employed in precision farming. Satellites have been used in precision farming for over 40 years, when Landsat 1 was launched into orbit in 1972. It was equipped with a multispectral sensor top leaders provided a spatial resolution of 80 m per pixel with revisit intervals of approximately 18 days.

Landsat 5 was launched in 1984 and collected imagery in the blue, green, red, near-infrared, and thermal bands at a spatial resolution of 30 m. The first application of remote sensing in precision agriculture sublingual when Landsat imagery of bare soil was used to estimate spatial cte abbvie in soil organic matter content.

The spatial resolution of imaging systems has improved from 80 m with Landsat to sub-meter resolution with GeoEye and WorldView, and the frequency deterioration improved from 18 days to 1 day with new satellite platforms, with significant advances in sensor performances.

The latest satellite, WorldView 3, cte abbvie launched in August 2014, is even capable of providing resolutions cte abbvie 0. The use of satellites in remote sensing therefore has great potential, but the spatial resolutions are cte abbvie sufficient for precision viticulture due career counseling in the narrow vine spacing.

Another limitation is the temporal resolution, and cloud cover that can occur at the time the satellite passes. Aircraft allow ground monitoring with wide flight range and high payload in terms of weight and dimensions, thus providing the ability to manage a large number cte abbvie sensors.

The aircraft bypasses some limitations of the satellite application by programming the image time acquisition and providing higher ground resolution, depending on the flying altitude.
